Cov yeeb nkab fittings yog ib lo lus sib sau ua ke rau cov khoom siv hauv cov kav dej siv rau kev sib txuas, kev tswj, kev hloov pauv, kev khiav dej num, kev sib khi, thiab kev txhawb nqa. Cov khoom muaj xws li steel hlau, stainless hlau, thiab yas. Raws li txoj cai, lawv tuaj yeem muab faib ua pob tw -welded, qhov (socket){3}}welded, threaded, thiab flanged hom. Lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev nyab xeeb thiab kev ua haujlwm ntawm cov kav dej.
Raws li daim ntawv thov, lawv tuaj yeem muab faib ua 6 pawg: hom kev sib txuas (xws li, flanges), hom kev hloov pauv (xws li, lub luj tshib), thiab txoj kab uas hla hloov hom (xws li, reducers). Txoj kev sib txuas npog cuaj hom, suav nrog vuam, threading, thiab clamps. Cov hlau thiab tsis yog-cov khoom siv hlau tuaj yeem hloov kho rau cov kev xav tau sib txawv thiab cov kev xav tau siab, thiab tau siv dav hauv petrochemical, engineering engineering, nuclear zog, thiab marine industries.
Cov yeeb nkab haum tus qauv tau pib muab faib ua ob lub tshuab loj: European (DIN) thiab Asmeskas (ANSI). Cov txheej txheem thoob ntiaj teb ISO 7005-1 tau koom ua ke los ntawm ob qho tib si hauv xyoo 1992. Tuam Tshoj tau maj mam tsim cov GB / T series ntawm lub teb chaws tus qauv, npog cov kev tsim thiab kev sim cov kev cai rau steel thiab yas yeeb nkab fittings, thiab siv lawv nyob rau hauv parallel nrog thoob ntiaj teb cov qauv xws li ASME thiab DIN, txhawb lub standardization ntawm thoob ntiaj teb pipeline engineering technology.
Steel yeeb nkab fittings yog tag nrho cov siab- bearing fittings. Raws li cov txheej txheem sib txawv, cov yeeb nkab fittings tau muab faib ua plaub pawg loj: taub qab-welded yeeb nkab fittings (sib faib ua welded thiab seamless hom), qhov (socket) -welded thiab threaded yeeb nkab fittings, thiab flanged yeeb nkab fittings.
